User Manual of EM760 High-Performance Inverter F00.17=0: set by F00.18 The upper frequency limit is set by F00.18. F00.17=1: AI1 F00.17=2: AI2 F00.17=3: AI3 F00.17=4: AI4 The upper frequency limit depends on AI (percentage) * F00.18. For the details ofAI1 to AI4, see 6.5.7. They have the same meaning. 100.00% is the percentage relative to the set value ofF00.18 (upper frequency limit). F00.17=5: High-frequency pulse input (X7) The upper frequency limit depends on HDI (percentage) * F00.18. See 6.5.3 for the details when X7 serves as the high-speed pulse input. They have the same meaning. 100.00% is the percentage relative to the set value ofF00.18 (upper frequency limit). F00.17=6:
Communication percentage setting of upper frequency limit ● If the master-slave communication (F10.05=1) is enabled, and the inverter works as the slave (F10.06=0), the actual upper frequency limit is “700FH (master-slave communication setting) * F10.08 (slave receiving proportional coefficient) * F00.18 (upper frequency limit)”, and the 700FH data range is -100.00% to 100.00%. ● For general communication (F10.05=0): F00.17=6, the actual upper frequency limit is “700AH (communication setting percentage of the upper frequency limit)*F00.18 (upper frequency limit)”. The data range of 700AH is 0.00% - 200.00% . F00.17=7:
communication setting The actual frequency limit is “7017H (communication setting of the upper frequency limit)”. The data range of 7017H is 0.00 - F00.16 (max. frequency). F00.18 is the highest frequency allowed after the inverter is started. It is represented by Fup, ranging from Fdown to Fmax; F00.19 is the lowest frequency allowed after the inverter is started. It is represented by Fdown, ranging from 0.00Hz to Fup. 1.
The upper and lower frequency limits should be set carefully according to the nameplate parameters and operating conditions of the actually controlled motor, and the motor should be prevented from long-time operation at the low frequency; otherwise, the motor life maybe shortened due to overheat. 2. Relationship of the maximum frequency, upper frequency limit and lower frequency limit: 0.00Hz ≤ Fdown ≤Fup ≤Fmax ≤600.00Hz; 3. When the set frequency is lower than F00.19 (lower frequency limit), the running mode is dependent on F15.33.
